Chicken Road

Chicken Road is an offline guide that lets you browse the hallmarks of British silver from 1697 to 1998. The app shows each assay office on a timeline, letting you tap a punch to reveal its date band and see how the marks narrow as you progress. It includes detailed pages for the ten assay offices, their operating years and the windows of town marks such as Chester, Glasgow and Sheffield. You can compare marks that never appeared together and see which pairs clash, for example a lion passant guardant ending in 1821 versus Victoria’s head starting in 1837. When you add a find, the app creates a simple stall ticket with the piece description, metal type, office, years and a line for each mark. The ticket can be copied as plain text for sharing or record‑keeping. The reference data follows Bradbury’s Book of Hallmarks and Jackson’s Silver & Gold Marks, covering town marks, sterling and Britannia standards, sovereign‑head duty marks and commemorative marks from 1935, 1953 and 1977. Date letters and makers’ marks are not included. All content is included in the app and works completely offline. With Chicken Road, your favorites, notes, progress, and personal data are stored only on your device, with no registration, accounts, or cloud synchronization required.
